psychic energy

To know oneself is the first step toward making flow a part of one's entire life. But just as there is no free lunch in the material economy, nothing comes free in the psychic one. If one is not willing to invest psychic energy in the internal reality of consciousness, and instead squanders it in chasing external rewards, one loses mastery of one's life, and ends up becoming a puppet of circumstances.
